Schwannomas are tumors originating from Schwann cells of the peripheral nerve sheath (neurilemma) of the neuroectoderm. Rarely, schwannomas can arise from the retroperitoneum and adrenal medulla. We describe a case of a 71-y-old woman who presented with an incidentally discovered adrenal tumor.
Ultrasound and computed tomography scans revealed a lesion with solid and cystic areas originating from the left adrenal gland. The patient underwent complete laparoscopic resection of the tumor and the left adrenal gland.
Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma measuring 5.5×5 3.7 cm. To our knowledge, few other cases of laparoscopic resection of adrenal schwannomas have been reported.
Because preoperative diagnosis of adrenal tumors is inconclusive, complete laparoscopic excision allows for definitive diagnosis with histological evaluation and represents the treatment of choice.
施万细胞瘤起源于神经外胚层周围神经鞘（神经膜）的施万细胞。罕见情况下，施万细胞瘤可起源于腹膜后和肾上腺髓质。我们描述了一例71岁女性患者，其肾上腺肿瘤为偶然发现。
超声和计算机断层扫描显示左肾上腺有一个包含实性和囊性区域的病变。患者接受了肿瘤及左肾上腺的完全腹腔镜切除术。
切除标本的组织病理学检查和免疫组化染色显示为一个大小为5.5×5×3.7 cm的良性施万细胞瘤。据我们所知，很少有其他肾上腺施万细胞瘤腹腔镜切除的病例报道。
由于肾上腺肿瘤的术前诊断不明确，完全腹腔镜切除可通过组织学评估进行明确诊断，是首选的治疗方法。
